I'll stick with the GUI, makes more sense to me. ;)

Jurjen posted : As far as I can see, the firmware is from Efficient Networks.

After over 18 hours of uptime, no spooky IP addresses any more. Just the time server sync every hour (a bit much, but I can live with that).

Thanks for the help, guys!

100% correct. Some versions of firmware (Windstream firmware if I recall) do exactly that.

The question was indeed (sorry if not properly formulated) where this came from. Who was demanding the address, why to the modem and no directly addressing the requested host by itself...?

I can only speculate about the orgins of the arp request.........

Since it's in the modems log I think the modem is doing it......
Some modems use arp to keep track of dhcp/static clients [active or inactive]

I changed the subnet to 255.255.255.0, so far no new strange addresses in the system log.

Sorry..........I overlooked the router.......

The net mask set in the modem is 255.255.0.0

You should change the subnet mask to 255.255.255.0
If the subnet mask is 255.255.0.0 the entire range of 192.168.0.0 is a part of the modems subnet
If this change has no effect I would do a factory reset and reconfigure

Yeah change the Subnet Masks on the modem and router's WAN to 255.255.255.0, 192.168.0.151 is a valid address in that subnet, still strange why you seeing that.

The modem is 192.168.3.1, the router's WAN is 192.168.3.2

Are you sure about this

What is the subnet mask of the modem

Most modems use arp to monitor it's lan devices

[SOLVED] Ghost IP addresses in system log SpeedStream 5200

Jurjen posted : Hello everybody,

It's not something severe (I think), but I have a weird issue with my Speedstream 5200 modem.

When I look in the system log, it's flooded with this kind of entries:

2011-09-10 14:52:12 E I |ARP                  |IP Address 192.168.0.151 was not found

My local network is in the subnet 192.168.1.x, the WAN side of the router and the LAN side of the modem is in subnet 192.168.3.x (router has a fixed IP, DHCP in the modem is off). So it's pretty logical that the address can't be found: it doesn't excist.

Where could the requests for these non-existing addresses come from? It's creating quite some traffic, because sometimes every 2 seconds there's a new entry like that.

What's wrong here?

Thanks!
